So this leads to the huge difference in the two approaches unlike with the fluxes of FVM, it's extremely difficult to place physical significance on the terms in the algebraic equations of FEM.įor practical purposes, this means that FVM fluxes have more physical significance but require a greater deal of effort for irregular geometries than FEM (which has the same effort no matter what). The variables get represented on the element by a shape function of the same form as the weight function. With FEM, you're integrating the governing partial differentials over an element or volume after it's multiplied by a weight function. This leads to your flux balance across the boundaries of the individual volumes. In FVM, you're integrated the governing equations over a volume or cell assuming a piece-wise linear variation of the relevant variables. Huh? What subset of modeling, beyond possibly the purely theoretical and academic, refers to FVM as just a subset of FEM? The two are different approaches with distinctly different application sets. It's worth noting that both code_aster and code_saturne are actually quite robust programs, as they were developed originally as in-house applications for EDF (who until recently was the world's largest electric company).

It'll provide a full suite of open source options, including those I mentioned, alternative FEA through code_aster and CFD through OpenFOAM and code_saturne. One avenue, if you're willing to look at linux distros, would be to check out CAELinux. You can do meshing and post-process visualization in Elmer itself, but using the other tools will really provide some significant enhancements.

Combined with FreeCad for part design, SALOME for meshing (if you're looking at more complex meshing than Elmer provides), and ParaView for visualizations, you've got a pretty robust, entry level, free and open-source avenue for FEA. I tend to use it quite a bit at work for exploring simple R&D concepts.
